Follow on milk - are we meant to give include this for our toddlers?

I’m scrolling through the grocery’s website, and i see Cow &Gate, Aptamil, SMA, Paediasure, Kendamil etc with products like “toddler milk formula,” for ages 1-3years.

I then read what’s in it and they have lots of nice vitamins etc and then I wondered - am I meant to be giving my 18 month old this stuff?

She was EBF, And still breast feeds, and she drinks cow milk, sometimes goat milk for the added protein it contains. Am I missing something or doing her a disservice not giving her these other products or should I be including it?

Thank you
